There has been much discussion in this forum about shaving soaps being reformulated to exclude tallow. Mostly the blame has been placed on pressure from those who oppose the use of animal products. Here's another theory:
I happened to catch one of those "how do they make it" programs on cable TV the other day, and they were talking about how bio-diesel is made. I had always thought it was made from vegetable oils, but the program pointed out that tallow is also used. So maybe the reformulation is driven by price competition: the makers of bio-diesel outbidding the makers of soaps? Or maybe it's a matter of volume? Why sell a few hundreds of pounds of tallow to the likes of G. F. Trumper when you can sell it by the ton to the folks who make bio-diesel?
